Siple DemiBold

Siple DemiBold by Tomoyuki Watanabe is a free geometric sans-serif with a calm, rounded voice. The letters feel built from simple circles and straight strokes, giving the font a neat modern rhythm, while details like the compact dot, single-storey forms, and broad curves keep it from turning cold.

It fits naturally in branding, app graphics, posters, packaging, and magazine cover lines where a free font needs to look clean but not sterile. Use it for short headlines, logos, title cards, or wayfinding-style labels, especially when you want smooth geometry and a slightly friendly tone instead of a hard corporate sans.
